"pip install somepackage" freezes powershell - python

I've been using python in both my office pc and my personal laptop and on both machines typing in powershell:
pip install somepackage
works normally.
Strangely enough, when I attempt to do it on my personal desktop, powershell remains on halt infinitely.
I found a solution for this by doing:
python -m pip install somepackage
The above is fine, and I can live with typing an extra 8 characters whenever I want to install a new package but I'm curious to understand what is happening.
Thanks :)
PS: I have added C:/Python27/Scripts to Path in the system variables already and it didn't solve the issue.

pip.exe is located in C:\Python27\Scripts. You need to add that folder to your PATH environment variable. If you added it to the system environment you need to start a new PowerShell console to make the change become effective.
If you want the path to become available in the current console you need to add it to the PATH variable in the current console as well (the console gets a copy of the environment when it starts, it doesn't pick up changes to the system or user environment at runtime):
$env:Path += ';C:\Python27\Scripts'
pip install somepackage
However, C:\Python27\Scripts not being included in the PATH should only result in an error message that PowerShell doesn't recognize the command. It shouldn't freeze the console. Perhaps there's some other cmdlet/command/function/alias named pip that gets executed instead. Try running Get-Command pip to verify that.

Multiple pip in \Scripts [duplicate]

I'm running into a weird error when trying to install Django on my computer.
This is the sequence that I typed into my command line:
C:\Python34> python get-pip.py
Requirement already up-to-date: pip in c:\python34\lib\site-packages
Cleaning up...
C:\Python34> pip install Django
'pip' is not recognized as an internal or external command,
operable program or batch file.
C:\Python34> lib\site-packages\pip install Django

What could be causing this?

You need to add the path of your pip installation to your PATH system variable. By default, pip is installed to C:\Python34\Scripts\pip (pip now comes bundled with new versions of python), so the path "C:\Python34\Scripts" needs to be added to your PATH variable.
To check if it is already in your PATH variable, type echo %PATH% at the CMD prompt
To add the path of your pip installation to your PATH variable, you can use the Control Panel or the setx command. For example:
setx PATH "%PATH%;C:\Python34\Scripts"
Note:
According to the official documentation, "[v]ariables set with setx variables are available in future command windows only, not in the current command window". In particular, you will need to start a new cmd.exe instance after entering the above command in order to utilize the new environment variable.
Thanks to Scott Bartell for pointing this out.
For Windows, when you install a package, you type:
python -m pip install [packagename]
As of now, version 3.7.3 I had a little bit of an issue with getting the right system variable.
Try this:
Type start %appdata% in cmd.
After that file explorer should pop up in ../AppData/Roaming.
Go back one directory and navigate to Local/Programs/Python/Python37-32/Scripts.
NOTE: The version number may be different so if you copy and paste the above file path it could not work.
After you do this you now have the correct location of your downloaded Python. Copy your file path by selecting the whole directory in the address bar.
Once you do that click the start icon and navigate to the Control Panel → System and Security → System. Then click "Advanced System Settings" on the left side of the panel.
Once there, click Environment Variables on the bottom right and there will be two boxes, an upper and a lower box. In the upper box: Click on the 'Path' Variable and click Edit located on the right. Click New and paste your directory Path. It should look something like this:
Click OK three times, open a new window of cmd and type: pip. See if it works.
For me the command:
set PATH=%PATH%;C:\Python34\Scripts
worked immediately (try after echo %PATH% and you will see that your path has the value C:\Python34\Scripts).
Thanks to: Adding a directory to the PATH environment variable in Windows
Alternate way.
If you don't want to add the PATH as the previous well written answers pointed out,
but you want to execute pip as your command then you can do that with py -m as prefix.
Given that you have to do it again and again.
eg.
py -m <command>
as in
py -m pip install --upgrade pip setuptools
Also make sure to have pip and py installed
The only way that worked on my Windows 10 machine was as follows:
py -3 -m pip install xxxxx
Also, the long method - it was a last resort after trying all previous answers:
C:\python27\scripts\pip.exe install [package].whl
This after cd in directory where the wheel is located.
As per Python 3.6 Documentation
It is possible that pip does not get installed by default. One
potential fix is:
python -m ensurepip --default-pip
Control Panel -> add/remove programs -> Python -> Modify -> optional Features (you can click everything) then press next -> Check "Add python to environment variables" -> Install
And that should solve your path issues, so jump to command prompt and you can use pip now.
Go to control Panel >> Uninstall or change Program and double click on Python XXX to modify install. Make sure PIP component is checked and install.
I was having the same problem just now.
After adding the proper folder (C:\Python33\Scripts) to the path, I still could not get pip to run. All it took was running
pip.exe install -package- instead of
pip install -package-.
Try going to Windows PowerShell or cmd prompt and typing:
python -m pip install openpyxl
In latest version Python 3.6.2 and above, is available in
C:\Program Files (x86)\Python36-32\Scripts
You can add the path to our environment variable path as below
Make sure you close your command prompt or Git after setting up your path. Also should you open your command prompt in administrator mode. This is example for Windows 10.
Use
set Path = `%PATH%;C:\Python34\;C:\Python27\Scripts`
Source
Or if you are using PyCharm (2017-03-03) like me, just change directory in terminal and install:
cd C:\Users\{user}\PycharmProjects\test\venv\Scripts
pip install ..
Most frequently it is:
in cmd.exe write
python -m pip install --user [name of your module here without brackets]
Even I'm new to this, but pip install django worked for me.
The path should be set as where the script folder of the Python installation is, i.e.C:\Python34\Scripts.
I suppose it's because Django is a framework which is based on Python, and that's why this directory structure has to be maintained while installing.
I have just installed Python 3.6.2.
I got the path as
C:\Users\USERNAME\AppData\Local\Programs\Python\Python36-32\Scripts
In Windows, open cmd and find the location of PYTHON_HOME using where python. Now add this location to your environment variable PATH using:
set PATH=%PATH%;<PYTHON_HOME>\Scripts
Or refer to this.
In Linux, open a terminal and find the location of PYTHON_HOME using which python. Now add the PYTHON_HOME/Scripts to the PATH variable using:
PATH=$PATH:<PYTHON_HOME>\Scripts
export PATH
You can try pip3. Something like:
pip3 install pandas
I was facing the same issue. Run Windows PowerShell as Administrator. It resolved my issue.
None of these actually worked for me, but running
python -m pip install -U pip
and then adding the specified directory to the PATH as suggested got it working
In your Python folder path in Terminal, just type
py -m pip
in order to check the current version of your pip.
You will also see a list of commands, you can use...
I think from Python 2.7.9 and higher pip comes pre installed and it will be in your scripts folder.
So you have to add the "scripts" folder to the path. Mine is installed in C:\Python27\Scripts. Check yours to see what your path is so that you can alter the below accordingly. Then go to PowerShell, paste the below code in PowerShell and hit Enter key. After that, reboot and your issue will be resolved.
[Environment]::SetEnvironmentVariable("Path", "$env:Path;C:\Python27\Scripts", "User")
In a Windows environment, just execute the below commands in a DOS shell.
path=%path%;D:\Program Files\python3.6.4\Scripts;
(new path=current path;path of the Python script folder)
I deleted the older version using the control panel and then installed the new version however the newer version was not reflecting pip even after adding the right paths in the environment variables. However, the thing that worked for me was deleting the folders of old python that were there in the local App folder even after uninstall. For me, the path was like below. Deleting this folder solved my issue
C:\Users\username\AppData\Local\Programs\Python38
'pip' is not recognized as an internal or external command
pip is a python module used to install packages. For your problem, there can be many reasons;
Restart CMD/Terminal
Environment variable is not set. pip is installed but environment variable is not set. Environment variable is a windows variable where pip path is saved, so it can be run at run time.
pip is not installed.
Restart CMD/Terminal
It is sometimes possible that you opened your command prompt or terminal before installing pip and now it just needs a restart to pick up the latest environment variables. It is worth trying just restarting your command prompt or terminal.
Environment Variable is Not Set
Open CMD and run this command to see the values set in the PATH environment variable.
echo %PATH%
This will echo the PATH environment variable like this;
You should check if your path exist in the echoed PATH list. For example, in my case, the path for pip.exe files is C:\Python310\Scripts. You can check this path yourself like this;
If you can find pip path and it does not exist the echoed PATH variable, then we need to add it. Copy the path like C:\Python310\Scripts.
Go to Start > This PC > Properties > Advance system settings >
Advanced > Environment Variables
As shown in the image above, Select Path, click Edit button and add the copied path. Restart the CMD and test pip command again.
pip is Not Installed
If pip is not installed, you can install it again by downloading latest python.exe setup from python.org website. Make sure you check mark the pip option as shown in the image below.
In the next step, check mark "Add Python to environment variables"
I had this same issue. You just need to go to your
C:\Python27\Scripts
and add it to environment variables. After path setting just run pip.exe file on C:\Python27\Scripts and then try pip in cmd. But if nothing happens try running all pip applications like pip2.7 and pip2.exe. And pip will work like a charm.
Small clarification: in "Windows 7 64 bit PC", after adding ...Python34\Scripts to the path variable, pip install pygame didn't work for me.
So I checked the "...Python34\Scripts" folder, it didn't have pip, but it had pip3 and pip3.4. So I ran pip3.4 install pygame .... .whl. It worked.
(Further open a command window in the same folder where you have the downloaded pygame...whl file.)

Question about pip using Python from Windows Store

I have python installed through windows store and I can install programs using pip, but when I try to run said programs, they fail to execute in powershell.
How can I make sure that the necessary "scripts" folder is in my path? I never faced these problems when installing from executable.
For example, "pip install ntfy" runs successfully in Powershell.
The command "ntfy send test" fails telling me the term is not part of a cmdlet, function, etc. etc.
The 'ntfy' program is located here /mnt/c/Users/vlouvet/AppData/Local/Packages/PythonSoftwareFoundation.Python.3.7_qbz5n2kfra8p0/LocalCache/local-packages/Python37/Scripts/ntfy.exe
What is the recommended way of editing my path so that programs installed via pip are available across windows store updates of the Python language?
In advance
I highly recommend you not to use python installed from the Windows Store, because you'll face such errors, and even more nasty ones.
The easy solution
Create a virtual environment on a more accessible folder, for example in C:\Users\<user>\python. To do so, do the following:
Using PowerShell, go to your user folder, using cd(Note that usually PowerShell already starts inside your user folder. This is an important setting to have, and if not, you should change your powershell starting point to this folder for the future.);
Now that you're in your user folder, type in the PowerShell mkdir python; cd python;
Now, to create a virtual environment, type python -m venv venv;
(You can verify that your virtual enviroment has been created by listing the folders, with the command ls);
You have created a virtual environment. Now, you need to activate it. To activate, run the following: ./venv/Scripts/activate;
Now, you have fully created and activated a virtual environment for your current PowerShell session. You can now install any packages / programs using pip.
After that, the only thing that you need to do is to add C:\Users\<user>\python\venv\Scripts to your Path, and you're good to go.
Caveats
By adding this folder to your Path, you may be using an outdated python version in the future, since the Scripts folder inside your virtual environment also adds a python executable that will be enabled in the path.
The recommended solution
As I stated before, I do not recommend to have the Microsoft Store version of python installed on your machine. That said, you're probably using it for the conveniences of having the latest Python version installed as soon as they're released. To alleviate this need while also getting rid of your MS Store Python. I recommend you using Chocolatey to install python (and pretty much any other programs for development).
What is Chocolatey?
Chocolatey is a package manager for Windows, pretty much like apt-get for Ubuntu Linux or HomeBrew for MacOS. By using a package manager, you get rid of the hassle of always having to execute the (mostly annoying) install wizards on windows.
To install Chocolatey:
Go to chocolatey.org/install and follow the install instructions;
(Recommended: Take a look on their documentation later to see what Chocolatey is capable of);
With Chocolatey installed, take a test drive and see if it is working properly by running choco -v in PowerShell;
By having Chocolatey installed, you can now run choco install python -y. Let's break down this command:
choco install -> The package installer of chocolatey
python -> the name of the package you want to install
-y -> This tells the installer to skip install verification by saying "Yes to All" scripts that will be executed in order to install a package.
With python installed from chocolatey, you can also see that Python is already added to your path - This means that any python package or executable installed globally will be now available on your machine!
Hope I could help you!
The above answer is good but I managed to get it to work by doing the following.
Find your installation under C:\Users\"your user"\AppData\Local\Packages it will be named something like PythonSoftwareFoundation.Python.3.7_qbz5n2kfra8p0
Open your windows settings in the start menu
In search type Environment variables. Edit environment variables for your account should pop up. Click it
In the top box find Path, click it
On the right Click new and enter C:\Users\"your user"\AppData\Local\Packages\"python install directory name from 1. here"\LocalCache\local-packages\Python37\Scripts inside the little box under the last item in the list
open a new cmd prompt and type the script you wanted it should work.
On Windows you can find the user base binary directory by running
python -m site --user-site
and replacing site-packages with Scripts.
For example, this could return
C:\Users\Username\AppData\Roaming\Python36\site-packages
so you would need to set your PATH to include
C:\Users\Username\AppData\Roaming\Python36\Scripts
You can set your user PATH permanently in the Control Panel. You may need to log out for the PATH changes to take effect.

Python hangs while executing pip and virtualenv and brings no results

I tried to set up a virtual environment for my project by executing virtualenv myenv. The folder seemed to be generated, but the command hung, and I couldn't execute another command. I had to close the console and restart cmd. The folder was generated, as I said, but I couldn't activate the virtual environment by venv\Scripts\activate.
I met the same behaviour while trying to execute pip freeze > requirements.txt. The file was generated, but it was empty, although I used a lot of packages in my project. When I executed just pip freeze, the list of packages was printed, but the command hung again, and I had to close the console again.
I tried both procedures many times, but with no success. I tried that in Windows cmd and Anaconda Prompt (Anaconda version: Anaconda3 2.4.1; Python: 3.5.1).
EDIT: when I tried to do this for the very first time some days ago, I succeeded in activating the virtual environment, but only for one time.
A simple solution to this (which does work) would be to use Powershell as an Administrator, instead of cmd.
Conversely, use cmd as an administrator, though I would recommend using the much-more powerful Powershell for any and all purposes!
Why this works:
A lot of commands need super-user rights (think root/ sudo in linux) in order to be properly executed.
Since there is no such thing as as sudo in Windows yet, you can implement it via admin privileges.

I can't use pip (Windows)

I'm wanting to learn machine learning, but it requires that I use 'pip.' I'm still very new to a lot of this stuff. I've installed Python 3.4 64-bit and get-py.py.
When I run pip install sklearn I get 'pip' is not recognized as an internal or external command, operable program or batch file.
Here's a screenshot of my environmental variable PATH

Any help would be greatly appreciated. I have checked out other posts where people had similar issues, but I tried various things and nothing worked.
Easiest solution is to just download a platform like Anaconda for example. It is Python with many libraries (sklearn, pandas, numpy, ...) and also with pip, all in a user-friendly Windows installer package, that takes care of everything for you.

If you really want to do it yourself, then
download get-pip.py (https://bootstrap.pypa.io/get-pip.py)
make sure you have Python installed and in your PATH, for example by running python --version in command prompt
Navigate to the directory, where you downloaded get-pip.py (in command prompt using the command cd).
Run the command python get-pip.py from a command prompt with admin privileges (possibly not needed, but just to make sure).
This should be all. Close your command prompt, open it again and run pip --version to test it. If it doesn't work, then search your computer for a file named pip.exe (most likely in your Python directory) and if you find it, add its path to your PATH variable (given the screenshot, I assume you know how to do this).
I downloaded Python 3.6 and the pip was installed on my system.
I found pip at below location:
C:\Users\Admin\AppData\Local\Programs\Python\Python36\Scripts
Also, before I found pip I used below command on my command prompt to install pyperclip:
python -m pip install pyperclip
For anyone that might have installed Python using the MSI installer, and ticked the box to include pip, but still gets the error 'pip' is not recognized as an internal or external command, operable program or batch file:
It looks like that the pip executable is installed in the \Scripts subdirectory of the Python installation, but that directory does not get automatically added to PATH.
For me, since I had installed Python 2.7, the directory was C:\Python27\Scripts. After adding this path to the PATH environment variable, and open a new CMD window, pip was available as a command.
I've made a workaround that will help you, copy the batch script below and modify it as specified:
#"PATH to python.exe" "PATH to pip.exe" %*
For example like this:
#"C:\programming\bin\python374\python.exe" "C:\programming\bin\python374\Scripts\pip.exe" %*
Save this file as pip.bat on Desktop and then move it to C:\Windows\system32.
For Python 3.7 or higher at least (as today is October 4th 2019) in the installation window you need to check the box "add to PATH" when you first install Python.
I'm late now, but just add python to your environment variables.
It´s explained in this short video, how to set up python to your environment variables:
https://www.youtube.com/watch?v=Y2q_b4ugPWk
after that pip should work on your cmd prompt, without cd to
"C:\Users\Admin\AppData\Local\Programs\Python\Python36\Scripts"
This is late but in case anyone runs across this issue, pip installed for me as "pip3". Once I used pip3 as my command and not pip, it worked fine. Threw me for quite a loop since I've been using Python for years.
PIP Install and Upgrade
Ensure you are accessing the right location while accessing pip as shown in my link above. Starting Python 3.4, it is included by default with the Python binary installers.
Environment Variable
It is also a good idea to update the environment variable if the path is not accessible by default, once the installation is complete.
If it is specifically pip you want you could install python again making sure to tick the install pip box which it sounds like you failed to upon initial installation.
